Ran into this metadata detection bug with the file name “Tengoku.Daimakyo.S01E06.100.Percent.Safe.Water.mkv”.
“100 Percent Safe Water” is the episode title. Plex detects this as “Episodes 6 to 100”, and thus creates episode files up to 100 using the same file. I think Plex should not count periods in whatever regex it uses to determine the episode number.
